Combining stylish looks with power sport timing and heart rate monitoring features, this mid-sized Timex Digital Fitness watch (model T5J031) can be worn by both men and women. It features a chest strap heart rate monitor, easily accessible function buttons, durable resin case, and comfortable resin strap with a stylish tapered profile. For integrating heart rate monitoring into your training, this watch enables you to track your avareage heart rate and pre-set target heart rate zones with data for time spent within that zone and alarms. It can also display data for calories burned and offers a recovery timer that measures your heart rate after a timed recovery during or after your workout. Sport timing features include:

100-hour chronograph with lap and split, either in large digits

27-lap memory with average heart rate per laps

100-hour countdown timer

Alarm with 5-minute backup

Month/day/date display with 12/24-hour time

3.5-year battery life

The Indiglo night-light uniformly lights the surface of the watch dial using patented blue electroluminescent lighting technology. It uses less battery power than most other watch illumination systems, enabling your watch battery to last longer. The Night Mode feature allows you to illuminate the Indiglo night-light for 3 seconds with any button press, regardless of the mode or function. The watch is water resistant to 30 meters (165 feet)--suitable for swimming but not for diving. All Timex heart rate monitor sensors have batteries that can be replaced by consumers without requiring them to be returned to the manufacturer.

I purchased this watch to replace an older Polar heart rate monitor with dead batteries in the chest strap and the monitor. The design of that product required me to send both units in for replacement by a Polar service center. The cost was nearly as much as the cost of this timex heart rate monitor.

I am so pleased with this product. The instructon manual was clearly written and easy to understand. There are just enough functions for me without loading the product up with things I will never use. That makes using it simple and I can remember how to use it without having to refresh my memory by repeatedly rereading the manual.

The monitor is an excellent watch when not using the heart rate features. Best of all I can change the batteries myself when the time comes without sending the thing off in the mail to a service center.

On top of all that the price was reasonable. This is one of those few purchases that exceeded my expectations because everything that it does, it does a little bit better than I had hoped for.

I bought this HRM to help me as I began a training program, and decided on this one rather than a Polar monitor because it was cheaper and because it was a Timex. It was easy to use out of the box (I ran later that day); I set the time and after fiddling a little with the buttons I was able to use the timer and HRM functions.

The chest strap is snug and comfortable; the watch is unisex but for women with tiny wrists it might be a bit too loose; I myself wear it the tightest possible setting.

Aesthetically it looks great. It's not something that I personally would go around wearing all the time, but it's easy to read and the buttons are easy to use. The indigo is not ideal for when I'm running on the street in the evening since it lights up the numbers rather than the whole face of the watch, but this is a tiny issue.

Overall, fantastic product, and I'm so glad that something this well-featured is availiable at such a competitive price from Timex.

1. The product does everything that it claims to do.2. The watch looks nice enough to wear all the time as your main watch.

3. The strap that needs to be used to send your heart beats is comfortable.4. You can learn the HRM quickly if you fool around with it a little bit. If you are a computer nerd, you will learn it in less that one hour.5. The only thing negative is that it uses batteries like crazy. I have to use a new battery every week and that costs $5. There is no shut off botton on the transmitter so it is constantly on and the battery drains.

Good.1.Improved elastic band and toggle lock.2.Coded digital transmitter, reduces interference,(May not work with gym machines as most of these still are analogue receivers.)3. Transmitter battery can be changed by user, costs $ 2.004. Watch battery can be changed at Sears Jewellery, less than $ 15.00

Bad.1.Gimmicky. Too many modes. Just about figured it out.2.The booklet describes all functions first and HRM set up last.3. If above XL male, the HRM strap may be short, loose elasticity due over stretch.

This is an elementary and reliable heart rate monitor. It is easy to use and durable. I have used it since February and now routinely wear it for all exercise. The watch has a stop watch, lap timer, alarm, hrm, calorie counter, max/min/ and average heart rate counter and tracks where you are in desired heart rate zone. This is a terrific product --works well and does just what it is supposed to do. I'd recommend buying a spare battery for the chest transmitter; it wore out after about 50 hours of exercise use.

After researching several HR writst monitors, I decided on the T5J031 for the following reasons: (1) the face is large enough to read without straining while exercising, (2) it's lightweight, (3) it has many features, and alerts when moving into/out of the different burn levels, (4) my everyday watch broke, and this monitor is also a watch, (5) the price was not outrageous, and (6) it's made by Timex. I am very satisfied with the purchase.

I bought this watch in June to help me with a running program that required a heart rate monitor. After reading reviews on Amazon for a number of watches, I bought this one and have been thrilled with it -- so much so that I bought one for my wife and talked my sister into buying one as well as she trains for a 10 mile race. This one does all of the basic functions that you want in a heart rate monitor -- tracking your heart rate with minimums and maximums, giving you 6 heart rate zones to choose from, warning you when you are outside of your target zone, etc. I used it within hours of unpacking the box. What it doesn't do is allow you to download your workout onto a computer after you are done, and it doesn't really have a good interval function that automatically takes you through a cycle of intervals -- you can get both of those functions on other watches, but for the price this one is does all of the basic stuff at a very good rate. I've lost 10 pounds in six weeks just using this watch, so I'd highly recommend it.
